A succinct technique for the extraction of the proximal femoral nail anti-rotation (PFNA) after unlocking failure: a case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionProximal femoral nail anti-rotation (PFNA) is a routine method to deal with intertrochanteric fractures in the elder population. It is challenging to remove PFNA in some cases as a result of stripping of blade heads. In this case presentation, we describe a novel technique using commonly available instruments that can be used to remove stripped, even broken anti-rotation blade where conventional methods have failed.
methodsThe subject underwent a PFNA removal surgery 15 months after the previous fixation. We encountered difficulties using the regular instrument to remove the anti-rotation blade. A 5-mm tungsten carbide bur was used to drill a single cortical hole at the end of the blade. Then double-strand steel wire was threaded through the hole, and the distal part was shaped into a circle which could tie to the extraction screw. Slide Hammer was applied to gently knock out the blade along the anatomical direction of the femoral neck.
resultsThe technique helped us successfully remove the anti-rotation blade and provided the patient with a satisfactory result.
conclusionThe use of a tungsten reamer and steel wire loop to remove the proximal femoral anti-rotation blade may provide a cost-effective and straightforward method of dealing with extraction failure.
